Additional Information

Road Crank

100% Pure Crank from Paul Component Engineering.

Our Road Cranks take advantage of the narrower chainstays found on road frames, and the narrow chainline of our High Flange hubs.

These cranks use a specially designed interlocking chain ring/crank interface. Four 7075 Aluminum chain ring bolts with T25 Torx heads bolt through the chain ring and into the reinforced spider on the crank arm.

We machine the crank arms from 2024 aluminum, a very strong and stiff material. They are given a high polish finish and optional black anodization. We currently make the Road Crank in two lengths: 165mm and 170mm.

The chain rings are machined out of 6.3mm thick aluminum plate; very sturdy. They're currently designed only to work with 18" chains (track and bmx), and are unpolished. Replacement chain rings are available.

Chain rings are available in two different patterns and seven different sizes. 32, 34, 36, 39, 44, 46 and 48 tooth rings are available in our Circles pattern. Additionally, 46 and 48 tooth rings are available in our "Royal Flush" suit of cards pattern.
